Supertech - Valve Locks single groove

Description

Some Supertech performance valves feature “radial-style” single groove on the valve stem and require matching single groove valve keepers. Single groove valves are preferred for performance orientated and race engines as the top part of the groove provides a cushion for the lock and aids in valve stem protection against uncontrolled and excessive valve movement. In addition, the single groove design greatly extends valve stem life by restricting rotation of the valve preventing accelerated wear by excess movement caused by the factory triple groove design. 2 valve locks required per valve
